Vibhūti-yoga in the Bhāgavata: The Lord’s Manifest Opulences and the Discipline of Control
तीर्थानां स्रोतसां गङ्गा समुद्र: सरसामहम् । आयुधानां धनुरहं त्रिपुरघ्नो धनुष्मताम् ॥ २० ॥
tīrthānāṁ srotasāṁ gaṅgā samudraḥ sarasām aham āyudhānāṁ dhanur ahaṁ tripura-ghno dhanuṣmatām
Among sacred places and flowing waters I am the holy, purifying Gaṅgā, and among still bodies of water I am the ocean. Among weapons I am the bow, and among those who wield weapons I am Lord Śiva, the destroyer of Tripura.
Lord Śiva used his bow to completely cover with arrows the three demoniac cities built by Maya Dānava.
In this verse, Krishna identifies the Gaṅgā as His own manifestation among sacred rivers, teaching that contact with the Gaṅgā is revered because it powerfully reminds devotees of the Lord’s presence and purity.
Krishna is describing His vibhūtis—His prominent manifestations—so He cites Śiva as Tripuraghna, famed for destroying Tripura with divine archery, showing that all extraordinary power and glory ultimately rest on the Lord.
Practice remembrance by linking greatness to Krishna: when you see a mighty river, the ocean, or exceptional skill, consciously recall that such excellence is a sign of the Supreme, strengthening gratitude and devotion.
